Taejo (Yi Seong-gye)

Founder and first king of Joseon, formerly a general who fought Japanese pirates and the Red Turbans

A general from the northeastern frontier, he took part in the recovery of the Ssangseong Commandery under King Gongmin, fought off the Red Turbans and crushed Japanese pirates at the Battle of Hwangsan in 1380. Sent to attack Liaodong in 1388, he cited four reasons against the campaign and turned his army back at Wihwado (the Wihwado Retreat); in power, he enacted the Gwajeon Law with the new Neo-Confucian scholar-officials. He took the throne in 1392, named the country Joseon and moved the capital to Hanyang. After the First Strife of Princes in 1398 killed Jeong Do-jeon and Crown Prince Bangseok, he gave up the throne.
